Digital Differential Analyzer Algorithm

This article is about a graphics algorithm. For the digital implementation of a Differential Analyzer, see Digital Differential Analyzer.

In computer graphics, a hardware or software implementation of a digital differential analyzer (DDA) is used for linear interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons. In its simplest implementation the DDA algorithm

Introduction To Computer Graphics

The Borland Graphics Interface (BGI) is a collection of functions and procedures that are often called as graphical toolkit which an application program may use to solve specific graphics problem. Turbo C++ graph unit (graphics.h) provides a complete set of library consisting of over 80 graphics routines that range from bit oriented routines high level calls.
